222 [March, 



tlie ground colour there are two varieties, one is light ochreous-brown 

 having conspicuously paler cream-coloured patches on the back of 

 several segments, the other variety is dark greyish-brown with paler 

 patches, sometimes of light cinnamon-brown, often palest on the fifth, 

 ninth, and tenth segments ; the head is much freckled with reddish- 

 brown, and has a brown conspicuous spot on the front of each lobe, 

 and another just above each papillus ; the dorsal line on the thoracic 

 segments is but just indicated by very short double black marks at their 

 divisions, but it is more complex on the other segments, being com- 

 posed of a fine central pale thread within two lines or series of brown 

 freckles, which widen gradually as they approach between the second 

 pairs of tubercles, and then as gradually contract towai'ds the end of 

 each segment ; these are followed in a parallel direction on either side 

 of the back by a pale line edged outside with a line of brown fi-eckles, 

 some lighter some darker, and after an interval of ground colour, by 

 the pale sub-dorsal stout line, edged on both sides with a thin line of 

 brown freckles ; the front pairs of warts are black on the fifth, sixth, 

 seventh, eighth, and ninth segments ; and the hind pairs, though pale 

 in part, are involved in a strong black mark which, flovving from them, 

 darkens the parts of both adjacent lines to the segmental division ; 

 sometimes, but not often, these black markings are present on the 

 four hinder segments, otherwise the warts only bear a black dot ; along 

 the side occurs a faint pale wavy line, edged below with black, but this 

 is interrupted for a space just behind each lateral black wart, and 

 again continued to the segmental division ; the spiracles are of the 

 ground colour, roundish-ovate in form, and strongly outlined with 

 black, and in front of each is a short lino of a few black freckles . 

 lines occur on the belly but are very faint ; each tubercular wart emits 

 a fine sliort bi'istly hair, and these hairs are rather numerous on the 

 head, the thirteenth segment, and anal legs. 



When full-fed, and beginning to contract for its change, the 

 coloui'iug of the larva is turned to a dingy smoky-green. 



Apparently it makes no appreciable cocoon, and a few days before 

 the moth is disclosed the pupa makes its way upwards towards the 

 surface of the earth. 



The pupa is about three-quarters of an inch in length, stoutest 

 across the ends of the wing-covers, where its diameter is a quarter of 

 an inch, and fi*om whence it tapers gradually to the end of the abdo- 

 men, which is furnished with a tapering projection, separating near 

 the end into two fine short points ; the surface of the thorax and 

 wing-covers smooth, the abdominal rings very finely punctate, their 

 divisions smooth, and of a dull violet-brown colour; all the other 

 colouring dark brown and glossy.
